REPEATING MECHANISM FOR TIMEPIECES.

SPECIFICATION forming part of Letters Patent No. 502,917, dated August 8, 1893.

I Application filed May 21, 1890. Serial No. 352,654. (No model.)

T0 at whom it may concern:

Be it known that I, FRED TERSTEGEN, a citizen of the United States, and a resident of Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Repeating Mechanism for Watches and other Timepieces, of which the following is a specification.

This invention relates to an improved repeating mechanism for watches and other time-pieces and to the manner of starting the repeating mechanism to strike the time by means of a winding-pinion and a train of gearing operated by said pinion.

The invention consists in setting the repeater motor-spring in action by a winding stem and pinion and a device operated by intermediate gearing forming part of the winding mechanism of the repeater motor for releasing the striking rack automatically, when the said motor-spring has been sufficiently retracted to return the striking mechanism to its normal position.

The invention further consists in preventing the over-winding of the repeater-motor and also the rewinding of the same until the time is fully struck, by providing a stop device which through suitable mechanism when the rack or racks are set, arrests the further retraction of the repeater-spring and holds the same until the time is fully struck, the said device being adapted to sustain any strain that may be put on the winding-pinion, as the result of attempting to over-wind.

The invention further consists in the construction and combination of parts and details, as will be fully described and set forth hereinafter, and finally pointed out in the claims.

In the accompanying drawings Figure l is a face view of my improved repeating mechanism for watches, the striking-racks being released and the parts in position for action. Fig. 1 is a sectional elevation of the hammeractuating mechanism of Fig. 1 taken from the direction of the arrow when the strikingracks are in their normal or initial position. Fig.

1 is a face view of a part of the front watchplate which carries the stem-driven train of the watch and the pendant-set connection with the wedge, used to prevent the striking mechanism from operating, while the hands are being set, by lifting the arbor 24, (shown in section,) and also used to break the connection of the gearing for transmitting motion from the winding-pinion to the repeatermotor, when the stem-driven train is brought to its hand-setting position. Fig. 1 is a section of the pendant of a watch, drawn on a larger scale, provided with the stem-springs by which the longitudinally-movable stemarbor is held in the required position. Fig. 1 represents a face view of a part of the front watch-plate, which carries the stem-driven train, and the wedge as modified to adapt it to operate in connection with the pendantset devices and repeating mechanism, to break the connection of the gearing used for transmitting motion from the winding pinion to the repeating mechanism and also used to connect the same with the windingpinion, when the stem-arbor is drawn or pulled out a short distance. Fig. 2 is a face view of a part of the watch-plates and showing the repeating mechanism in its normal position of rest. Fig. 3 is a similar view, showing the repeating mechanism brought to a striking position and the striking-racks disconnected from the driving gear of the motor-spring and a stop mechanism brought in action to prevent further winding of the motor-spring. Fig. 4 is a face view of a part of the front-plate of a watch, which carries the stem-driven train and the yoke lever setting mechanism for the same, connected with the wedge, modified to adapt the same to be operated by the yoke-lever setting mechanism when the stem-driven train is brought to its hand-setting position. Fig. 5 is a sectional edge elevation of a portion of a watch, showing the location and arrangement of the set of gearing, by which the motor-spring of the repeating mechanism is retracted, also showing the going spring-barrel in connection with the striking-racks. Fig. 5" is a similar view, showing the connection of the gearing broken between the barrel-arbor wheel of the repeater-motor and the winding pinion by the action of the wedge. Fig. (3 is a face view of a part of the watch, showing a stop mechanism for the moderatinggear arranged on the rackreleasing lever to hold the motor-spring in condition to act, also showing another gearing connection with the arbor-wheel of the repeater-motor. Fig.

6 is a face view of a part of the exterior of the front plate of the watch, showingthe gearing in connection with the stem-driven train. Fig. 6" is a sectional edge elevation of a portion of a watch, showing the winding-pinion and crown-wheel and the set of gearing for actuating the repeater-motor arranged through the watch-plates and acted upon by the yokelever setting mechanism to break the connection of the gearing that transmits the motion of the crown-wheel to the repeater motor.

Referring to the drawings, Sheet II, a winding-stem D is suitably connected with a wheel or winding-pinion 1 of a watch; the said pinion engages a crown-wheel2 as shown in Figs. 4, 5 and 6, which is placed under a yoke Y pivoted to the watch-plate A and held in place by a cap and screw as usual. At one end of the yoke is pivoted an intermediate winding-wheel 3 engaging the barrel-arbor wheel 4, when the yoke is in its winding position. 5 is the intermediate setting-wheel for transmitting the motion of the crownwheel to the dial-wheels, when the yoke is in its setting position. 7 is the cannon-pinion, placed on the center-post or minute-hand arbor 8, and 6 is a suitable wheel that connects the setting wheel 5 with the cannonpinion. These wheels are usually called dialwheels.

The above described mechanism of a stem winding and setting watch is of well known construction. I will now describe in detail my novel devices for operating a repeating mechanism by means of a stem-winding pinion.

On the under side of the watch-plate or bridge A is placed a wheel 20, which is held in place by a bridge 0, as shown in Figs. 5 and 5, or is attached in any other suitable manner in such a position that the said wheel 20 is engaged by the winding-pinion 1 and turned thereby. The wheel 20 is provided with ratchet-teeth 21, projecting from its upper side near its center-hole and engaging similar teeth 22 on the under side of a wheel 23, attached to a round arbor 24, which is passed through the center-hole of wheel 20 and bridge 0, and projecting below the same, so that the said arbor can be engaged by a wedge on a spring arm F, adapted to push or shift the same in the bridge 0, whereby its ratchetteeth 22 can disconnect the ratchet-teeth 21 of wheel 20 in order that the connection for transmitting motion from the winding-pinion to the repeater motor can be broken, when the dial-wheels forset ting the hands are operated by the winding-pinion 1, as will be hereinafter described. A suitable spring Z) presses by its free end upon the top or center-head of the wheel to keep its ratchet-teeth in engagement with the ratchetteeth of wheel 20. The said wheel 20 is turned by the winding-pinion 1 in either direction, but the arrangement of the parts is such, that when the winding-pinion is turned to the right, the wheel 23 is unlocked or disengaged by the ratchet-teeth 21 of wheel 20 and the motion of the winding-pinion is transmitted to the barrel-arbor wheel 4, which winds the motorspring of the time mechanism. But by turning the winding-pinion to the left or reverse direction, the motion of the sameis transmitted by the Wheel 20 to the wheel 23 by its clutch-device 21 engaging and locking the clutch-device 22 of the wheel The Wheel 23 engages the wheel 25 suitably fastened to the arbor 26 of the spring-barrel 27 for retracting the motor-spring of the repeating mechanism and the wheel 25 is held by a pawl or click 0 controlled by its spring 0 when it is rotated. The said click and spring are pivoted to the watch-plate and shown in Figs. 1, 2, 3 and 6.

28 is a shifting wheel or pinion for transmitting motion from the spring-barrel 27 to the striking-racks 30 and 31 and shown in Figs. 3 and 5, and is also used for releasing the said racks so that they can move to a striking position in the following manner: The hour rack 00 is attached to a gear-wheel 29 preferably shown as a segment in Figs. 1, 2 and 3, pivoted to a stud projecting above the watch-plate or bridge A and which is engaged by the wheel or pinion 28; the said pinion is pivoted to a movable bridge orlever 32 suitably pivoted at q to the watch plate or bridge A and is controlled by its spring at which presses the said lever with its pinion 28 toward the toothed spring-barrel 27 and the said pinion in gear therewith as shown in Figs. 1 and 2. The lever 32 is also provided with a projection or finger by which the same is turned aside by a stud or guide-device 3% attached to the wheel 25, when the same is turned around by the winding-pinion 1 and stem D as shown in Fig. 3, whereby the pinion 28 is shifted out of gear with the spring-barrel wheel 27 and thereby disconnects the segmental gear-wheel29 with its rack 30 from the motive power or springbarrel 27. A toothed lever or sector 35 is provided with an hour or snail-piece 30 arranged approximately in line with the circle of its teeth and is engaged and pressed by its spring WV toward the hour-snail Z. The said sector 35 gears into the segmental-wheel 29, and turns the said wheel with its hour-rack 30 to a striking position, as soon as the pinion 28 is shifted out of gear with the spring-barrel wheel 27, as shown in Figs. 1 and 3. Above or upon the gear-wheel 29 is placed a fiveminute rack 31, which is moved by its rackspring X toward the snail K. The said minute-rack is provided near its snail-piece 37 with an incut 38 having a shoulder 30 acting on a stop-lever 40 which is set thereby with its projection 41 in the path before the stud orguide-device 31 attached to the arbor-wheel 25, as soon as the pinion 28 is shifted out of gear with the spring-barrel wheel 27, thereby releasing the racks as shown in Fig. The said stop-lever is pivoted to the watch-plate A and is controlled by its spring a. By turning the arbor-wheel 25 a little more than is necessary to move the releasing lever 32, the latter with its finger 33, is pressed by its spring a behind the said stud or guide-device 34, which is prevented now from further turning and stopped by the projection 41 of the stop-lever 40 as shown in Fig. 1. The spring-barrel wheel 27 drives the moderating-gear m, provided with an escapement I, and is also engaged by the pinion 28 which is in gear with the segmental-wheel 29 that moves the hour-rack 30 and its sector back, whereby the rackteeth engage thehourhammer-tooth 5O pivoted below the other hammer tooth 54 and shown separately in Fig. 3, which comes in contact with the pin 52 attached to the hour-hammer 51, and actuates the same, and the hammer is forced by its spring 53 against the gong-spring G shown in Figs. 1 and 1. After the hours are struck a pin 0 attached to the segmentalwheel 29 comes in contact with the edge of the striking-rack 31 and turns the same back whereby the rack-teeth engage the upper hammer-tooth 54 that operates the minute hammer 57 in the following manner: The hammer 57 is provided with a staff 56 which is pivoted between the watch plates A A and which has one end (which is preferably squared), projecting through the plate A upon which is pivoted a finger or crank 55 which is engaged by the said hammer tooth 5t and communicates its motion to the said hammer 57 as shown in Figs. 1, 1, and swings said hammer which is engaged by its spring 58 hearing against a pin 59 provided for it and forced against the gong-spring G as shownin Fig. 1. After the striking has taken place the incut 38.0f the minute-rack 31 comes in contact with the stop-lever 40, which is caused by its spring 3 to turn into the same and its projection 41 is set thereby out of the way of the stud or guide-device 34: of Wheel 25, which can now be moved again by turning the winding-pinion 1 as before described.

Fig. 2 shows theposition of the mechanism after the striking has been finished and the pin 0 attached to the segmental-wheel 29, pro jecting from its under side bears against the end of a slot a, provided for it in the watchplate or bridge A,thereby stopping the motion of the racks and the moderating-gear. The springs 60 for returning the hammer-teeth operate as usual.

If desired, quarter and minute-striking devices may be arranged in connection with the hour-rack 30 in which case ditferently divided striking-racks are employed. The hour rack 30 and segmental-wheel 29 can also be formed as one wheel, instead of being separate wheels.

From the foregoing description it will be understood that the arbor-wheel 25 has to be turned once around, whereby the motor-spring is retracted,the repeating mechanism released and the further winding is stopped, until the repeating mechanism has finished striking the time and is then ready for another operation.

In Fig. 6 is shown the releasing-lever 32 modified and provided with astop attachment 61 for the escapementl of the moderatinggear, and consisting of ashort piece of springwire or a pin fastened to the1ever32 and projecting downwardly through the opening of the watch-bridge A,so that the same comes in contact with the escapement and checks the moderating-gear when the racks are to be released by disconneeting the pinion 28 from the spring-barrel wheel 27 in case the arbor-wheel 25 should not be turned fast enough and thereby the lever 32 should be delayed in dropping off the stud or guide-device 34. The said stud 31 is also shown half round, so that the said lever can be released more quickly. Instead of one stud or guide-device 341, two or more can be placed on the gearing, if desired, to start the striking mechanism as it depends entirely on the revolution of the spring-barrel or part thereof and the distance it has to travel, to return the striking-racks to their normal position.

The arbor-wheel is also shown without the use of the stop-leveretO for the purpose as before described to stop the Wheel from further turning, when the racks are being released. The main object of the said stop-lever is to prevent an over-winding of the motor-spring, while the repeating mechanism is in the position for action.

In order that the hands of the watch may be set either forward or backward by the winding-pinion 1 without interfering with the turning of the same, the connections for transmitting motion through the special gearing to the repeater-motor can be broken or disconnected in the following manner: In Figs. 5 and 5 a round arbor 24: is attached to the. wheel 23, which passes loosely through the wheel 20 and bridge 0 and projects through the same, so that the said arbor can be engaged by the free end of a wedge F which acts upon the rounded or beveled end of the arbor 24-, so that its wheel 23 with the ratchet-teeth 22 can be disconnected from the ratchet-teeth 21 of wheel 20. A suitable spring Z) presses by its free end on the top or center-head of the wheel 23 to keep its ratchet-teeth in engagement with the ratchet-teeth of wheel 20, when the wedge F is not brought in contact with the arbor 24 as shown in Fig. 5.

In pendant-set watches the operation isillustrated in Figs. 1 1 and 5. In the pendant d of a watch-ease is placed a case-sleeve carrying the stem-springs d which catch the stem in the annular grooves (Z and d formed in the stem-arbor D. In Fig. 1 the stem-arbor is pressed inwardly or the stem-springs catch in the groove (1 which is known as the windingposition and when the said stem-arbor is drawn out ashort distance until the stemsprings catch the groove d", it is known to be in the hand-setting position. \Vhen the stem D is applied to the winding-pinion 1 as shown in Fig. 1", and pressed inwardly, the sliding or push-pin (1 the end whereof within the winding-pinion bears against the end of the stem, is forced against: the end f of the wedge F and presses the same out of connection with the arbor 24, which is pressed down by its spring 1), whereby the wheel 23 with its ratchetteeth 22 will be connected with the ratchetteeth 21 of wheel 20 and the gearing for transmitting motion to the repeater-motor is connected with the winding-pinion 1 as shown in Fig. 5. But when the stem is drawn out, the wedge F follows the motion of the same and being released, its beveled edge or incline f engages and swings under the rounded end of the arbor 24:,which is thereby raised upon the top or face of the said wedge F, whereby the wheel 23 with its ratchet-teeth 22 will be disconnected from the ratchet-teeth 21 of wheel 20 as shown in Fig. 5. The connection between the winding-pinion 1 and the repeatermotor now being broken, the turning of the winding-pinion in connection with the handsetting gearing can be done in either direction, as the repeater cannot be operated, while the hands are set. The wedge may be provided with a slot or fork and connected thereby with a push-pin or stem-arbor or the push-pin or stem-arbor maybe provided with an annular groove having shoulders which act upon thelever to give it a swinging movement from and to the arbor 24;.

In lever-set watches the operation is illustrated in Figsi and 5 in connection with the wedge F that is movable laterally to press the arbor up to disconnect the winding-pinion from the repeater motor. The said wedge being modified carries a pin f projecting downwardly and through an opening or slot f provided for it in the watch-plate A, the said pin bears against the edge e of the setting-piece e which is placed on the under or opposite side of the said watch-plate where it is in connection with the yoke-lever E, provided with a pin e which turns the said setting piece 8 whereby its edge 6 bearing against a pin or projection 1 of the yoke Y turns the same, so that its wheel 3 will be disconnected from the barrel-arbor wheel i of the time mechanism when the yoke-lever Eis being drawn out in the direction of the arrow to its hand-setting position, in the usual manner.

The above described yoke-setting mechanism is of well known construction and is fully described and shown in my application Serial No. 346,781 now pending, and is also shown in Fig. 1 of the present application in dotted lines, (the watch being reversed) in connection with my novel wedge F for operating the arbor 2st of wheel 23. The wedge F by its pin f being in connection with the said setting-piece 6 will be moved or swung to the position shown by dotted lines, when the yoke-lever E is drawn out, whereby the inclined or beveled edge f 2 of the said wedge F engages and moves under the rounded end of the arbor2 l which is raised and shifted thereby until the same rests upon the top or face side of the said wedge F, whereby as before stated the wheel 23 on the said arbor with its ratchet-teeth 22 is disconnected from the ratchet-teeth 21 of wheel 20 and the connection between the winding-pinion 1 and the repeater-motor is broken, so that the said winding-pinion and stem-driven train are only in gear with the dial-wheels as usual for setting the hands.

Instead of a wedge F as before described, used for disconnecting the special gearing between the winding-pinion and the repeatermotor, when the stem-driven train is brought to the hand-setting position, a similar wedge J, shown in Fig. 1 may be used in connection with a longitudinally-movable stem D and arranged in the pendant (Z of a watch-case as described and shown in Fig. 1. The wedge J is set by the push-pin (Z through the inwardly pressed stem D in contact with the beveled end of the arbor 24 so that its beveled edge 7" is fully swung under the said arbor, whereby the wheel 23 attached thereto with its ratchet-teeth 22 is disconnected from the ratchet-teeth 21 of wheel 20 and the stem by this arrangement can be turned to the left or reverse from that of winding the watch as usual, as the special gearing is placed entirely out of action, and also by this arrangement the wedge J does not require a connection with the setting mechanism of the yokelever as before described. The gearing of the repeater-motor is brought in action only when the said stem-arbor is so drawn out that the stem-springs catch the groove (1 whereby the said wedge Jfollows the motion of the stem and releases the arbor 21 of wheel 23, which by its spring Z2 (shown in Fig. 5) is pressed down and its ratchet-teeth 22 are brought in engagement with the ratchet-teeth 21 of wheel 20 and the gearing for transmitting the motion to the repeater-motor is connected with the winding-pinion.

In place of the ratchet-teeth arranged on wheel 20, the hole of the same may be made square and the wheel 23 provided with a square arbor, which is shifted into the wheel 20, and its beveled end can be engaged by the said wedge J and act thereon so that when the said wedge is set by the push-pin and inwardly-pressed stem under the said beveled arbor, the same is shifted upward and the wheel 23 brought out of gear with the arborwhecl 25.

Fig 6 shows the front or exterior side of the plate A whereon the dial-wheels for setting the minute-hand are placed and is of well known construction. In this figure and in connection with Figs. 6 and 6 is illustrated the manner of connecting the special gearing for retracting the repeater-1n otor with the crown-wheel 2, which receives motion from the winding-pinion 1, instead of being connected directly with the said pinion. The said wheel 2 engages a wheel U, provided with a center-hole through which an arbor T is placed, which projects through the watchplates A and A. On the arbor T is arranged on one end a Hat head t provided with an oblong hole '6, of which one edge on its under side is rounded off or beveled down and the IIO other under edge of the hole is sharpened and the said head 25 on the arborT rests upon the wheel U in such a manner, that the ratchettoot'n a provided for or attached to the wheel U on its face side is placed into the said hole t of the head if so that the ratchettooth it engages and bears against the sharp edge and forms a clutch or coupling device, whereby the wheel U can turn the head 25 on arbor T and thereby the wheel V, placed on a square arranged on the other end of the said arbor and which is in gear with the arbor-wheel 25 retracting the motor-spring of the repeating mechanism. The wheel U can be turned by the wheel 2 in either direction by the winding-pinion l. The arrangement of the parts is such, that when the windingpinion is turned to the right, the head 25 on the arbor T is unlocked or disengaged by the wheel U and the motion of the winding-pinion is transmitted by the wheels 2 and S to the wheel 4 which winds the motor-spring of the time mechanism. But by turning the winding-pinion to the left or reverse direction, the motion of the same is transmitted by the wheels 2, and U to the wheel V by its clutch-device to engaging and locking the clutch-device t arranged on the arbor T. The free end of aspring t presses upon the said head on the arbor, thereby keeping the locking-device of the same in engagement with the wheel U.

The locking device t of the arbor T can be disconnected from the ratchet-tooth a of the wheel U through the mechanism connected with the yoke-lever E. The said yoke-lever is provided with a pin 6 which comes in contact with the setting-piece 6 provided with an arm 6 which engages the projection y of the yoke Y and turns the same in the usual manner, when the yoke-lever E is drawn outto its setting position.

The setting-piece e is provided with a beveled stud a which operates a spring-bar t for shifting the clutch or locking device t of the arbor T from the ratchet-tooth u of the wheel U in the following manner: The spring-bar t is provided with a hole t and a groove i and through the said hole the arbor T is placed so that its head 25, provided with a collar i rests in the groove i of the spring-bar t and the arbor T is shifted when the beveled stud e of the setting-piece e is turned under the free end of the said spring-bar, whereby the same is pressed or bent upward, and its groove i lifts thereby the head ton the arbor T away from the ratchet-tooth 'tl/ of wheel U. The said beveled stud e on the setting-piece e is turned under the said spring-bar, when the yoke-lever E is drawn out to its setting position, as shown in Fig. 6 By pushing the yoke-lever back to its initial position, the setting-piece e is turned by its spring 0', so that its beveled stud c is pressed away from under the spring-bar 25 which being released therefrom snaps down and the spring t pressing on the head on arbor T with its clutchdevice if is brought in connection again with the ratchet-tooth u of wheel U as shown in Fig. 6 whereby the motion of the windingpinion is transmitted to the gearing of the repeater-motor.

The wheel U and arbor T with spring bar if operated by the setting piece a in connection with the yoke lever E and the yoke-shifting mechanism for setting the hands are not claimed in this application.

The hammers for striking the time are arranged between the watch-plates A and A, and shown in Fig. 1. The shorter hammer 51 is pivoted to tho watch-plate A by a hollow screw-stud provided with a head and held therebyin place. Through the said hollow screw-stud extends the arbor or staif 56 of the hammer 57, firmly attached thereto and provided on its outer end with a square, upon which the finger or crank 55 is placed, which communicates the motion of hammer-tooth 54 to the hammer. The arm of the said hammer 57 is reduced in thickness so as to form a recess for the shorter hammer 51, so as to allow both hammers to be pivoted on the same center one above the other, and to occupy the same space between the plates.

I do not claim broadly the winding pinion in gear with the crown-wheel and the winding parts for retracting the repeater motor, as these parts are not connected directly with the winding pinion as in my application Serial No. 346,7SO-my present invention being limited to connecting those parts with a wheel for retracting the repeater motor as shown and described herein without giving a backward motion to the wheel V and arbor T.
